WATER-MOTOR.-

sPBcIrICA'rIoN forming part of Letters Patent No. 368,090, dated August 9, ist?` Application filed MarchlB, XPH Serial No. 232,065. (No model.) Y

To all 1071.071?, it may concern:

Beit known that I, FRANK A. HINDs, a citi- `zen of the United States, anda resident of /Vatertown, in the county of Jefferson aud State of New York, have invented certain new and useful Improvements in Tater-Motors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the io art to which it appertains to make and use the same, reference heilig had to the accompany ing drawings, which form a part of this specification, and in which-- Figure l -is a vertical longitudinal central :5 sectional view of my improved water-motor, taken on the plane indicated by line av zr, Fig. 2. Fig. 2 is a transverse vertical sectional View of the same, taken on the plane indicated byline y y, Fig. 1. Fig. 3 is a detail view of 2o the valve. Fig. 4 is a plan view of the valve, taken from the forward side thereof. Fig. 5 is a detail view of the valve seat, and Fig. 6 is a perspective detail view of the compound joint formed at the inner ends of the three pitmen. l i l The same letters of reference indicate corresponding parts in all the figures.`

This invention relates tfo water-motors; and its object is to obtain increased efficiency in 3o operation by diminishing the loss from friction in a motor of this class adapted to be operated by water under pressure.

Vith this object in View my invention consists in the improved construction, arrangenient, and combination of parts of a watermotor which is an improvement on the invention for which I have filed application for Letters Patent of the United States, Serial No. 231,204, and which will be hereinafter fully described and claimed. f

-In the present application I have shown and described the flanged hub, the light metallic ring, and the flexible diaphragm, but have not claimed them herein, as they were fully shown,

4 5 described, and clai med i n the application above referred to.

Referring to the several parts by letter, A indicates the main shaft or crankshaft of my improved motor, which is supported and turns 5o in central bearings, C B, in the two ends of the main casing of the motor, as shown, D indicating the valve chamber. Upon the crankshaft A, within the valve-chamber D, is loosely mounted the valve J, the interior space in the tubular neck J of the valve being larger than the diameter of the crank-shaft; and the valve is caused to turn with the shaft A by means of the clutch-ring K, which is rigidly but ad- .justably secured upon the shaft and engages with the notched rear end of the tubular neck of the valve. The operative face of the valve is formed with the large semicircular recess JA2 and amuch smaller semicircular recess, J", opening together and both concentric with the shaft A, the operative face of the valve being also formed with the wings T T, arranged as shown. The forward edge of the valve bears against or comes in contact with the valveseat F, Which is formed with three inlet-ports, a b c, arranged4 equidistant from each other around a circle whose center is the crankshaft.

E E Eindicate the passages which lead from each of the inlet-ports in the valve-seat to the space behind the pistons.

Upon the rear end of the tubular valvestem is secured or cast the angedhub U, the flange Uof which extends out at right angles tothe valve-stem and bears with its front side against the light metallic ring W', which is y secured to the inner edge of the annular flexible diaphragm W, which is secured to the annular interior shoulder, D', ofthe valve-chamber D.

' O O O indicate the pitmen, the inner converging end ofeach pitman being reduced and formed with a ring, O', and a segmental shoulder, O2, so that when the rings O are titted on the crank-pin P the segmental shoulders O2 of one pitman fit over the outside ofthe rings of the other connectingrods or pitmen, and t-hus transmits its power through all the ringsto the crank-pin, the three rings fitting on the crankpin, one occupying that portion of the pin nearest the crank,another the middle, and the third occupying the portion nearest the outer end of the crank-pin, the ring ends ofthe pitmen thus forming a compound joint.

V indicates the disk, which is secured by screws to the inner side ofthe rear head of the valvechamber, encircling the crank-shaft and holding in place packing, which prevents the leakage of waterthrough the journal C.

ICO

G indicates the main exhaust-passage, and H the outlet.

The above-described parts are old, forming a part of my previous application before referred to,and I do not therefore desire to claim them here, per se.

S S S indicate the covers, which form part of the outer casing of the motor, the passages E previously described leading through ports e into the spa'ccs covered by these covers S, and to the flange s of each cover S is bolted, by means of bolts passing through its fiangei1 and the cover-fiange s, acylinder, R. the length of which is rather greater than its diameter, although this :is not of course an essential point, as the proportions of the cylinder may vary. Vthin these cylinders fit and slide the pistons Q,which are made of sufficient length in the direction oftheir axes, so that they will not require a guide to make them run smoothly in the cylinders, and these pistons Q are pivotally connected to the outer ends of' the pitmen O, being formed at the center of their heads with the raised 0r cup portion Q', in which the outer ends of thepitmen extend and in which they are pivotally secured by means of a pivot-bolt, T, each of the said bolts passing transversely through the walls of the cupshaped extension Q of its piston and transversely through the outer end ofits pitman, as shown clearly in Fig. l of the drawings; and each piston is packed by apacking, U, made of leather, rubber, or other suitable material, in the form of a cup-shaped ring, as shown, the said cup-shapedring packing being secured in its operative position on the back or upper end of its piston by means of a metal ring, u, which is screwed down to the piston-head on theinner annular edge 0f the cupshaped packing, as shown; and the said rings, encircling the raised cup-shaped portion of the pistons extending around the ends of the transverse pivot-bolts T, will render it impossible for the said pivot-bolts to work loose out of their operative positions.

rlhe cylinders R are preferably lined with a removable hard-metal lining, R', which may be easily and cheaply renewed when worn out.

In the center of the top cover, S, I arrange a removable plug, S", and in the center of the cup-shaped portion Q of the top piston I arrang'e a similar removable plug, Q; and it will be seen that both of these plugs may be removed for the purpose of oiling the bearing at that end of the upper connecting-rod or ptman, while the outer bearings of the other pitmen may be oiled from the inside, as will be seen.

The valve J and the other parts A,described in my previous application before referred to operate in precisely the same manner as set forth in that application, and when the water under pressure passes through any one of the passages E into the space back of that piston it will be readily seen that it will force the said piston out in its cylinder, the outer annular edge of the cup-shaped packing of the piston being held out closely against the walls of the cylinder, thus effectual] y packing the piston in the usual manner of this form of packing. The pistons are successively reciprocated one after the other inthe same manner as the pistons in my previous application before referred to, and I will not therefore describe their opcration or that of the valve, 85e., in detail.

I have shown and described three pistons and pitmen working upon one crank; but the shaft may be worked with any number of pistons from one upward.

A large fly or balance wheel is mounted on the outer end of the main shaft, and by means of a suitable belt passing around the said wheel power is transmitted to operate any desired machinery. The momentum 0f the y-wheel is necessary where only one or two pistons are used; but with three or more pistons the iiywheel is not so essential.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my improved water-motor will be readily understood.

It will beseen that my invention is simple and strong in construction and exceedingly efficient in its operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The combination, with the cylinder, of the longvpiston formed with the eupshaped head, the pivotbolt extending transversely through the said head and the outer end of the pitman, the annular cup shaped packing ring, the metal retaining-ring secured to the piston-head on the inner edge of the cup-shaped packing` ring and extending around the ends of the transverse pivot-bolt, and the passage for conducting water behind the piston head, substantiall y as set forth.

VIn testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

FRANK A. HINDS.
